hey guys a bought a 1991 dx hatch with a d16a6 swap but its still dpfi it runs good very strong engine but it burns so much oil where do i start with diagnosing the problem?! im burning a quart week and it smells sweat all the time....

 

Is it smoking, if so when? Mine burned a lot of oil, it would burn a lot off after a long decel.

First thing is to check the simple things - make sure the oil level isn't too high, clean the PCV system and make sure that is all in order, check the valve cover gasket, other seals for signs of leakage.

In my case, I replaced the valve stem seals first (after checking the easy stuff), which didn't solve it. Re-ringing the pistons ultimately solved the issue and it ran great afterwards.

 

so ya it smokes alot when its not warmed up. then like you said long decels i live in a town with alot of mountains. it also smkes a big cloud some times when i go to pull away from a stop light to. i re did my valuve cover gasket and the spark plug gaskets also and no luck so maybe ill give the valve seals a go next. would it still have good compression if the rings were bad?!

 

Sounds like mine, and yeah it will have compression but the oil control rings can be bad, so there may be oil getting by them.

 

lol fun fun i can do the valve seals my self but i wonder what it would cost to have a machine shop do my rings! i just bought every thing to do a mpfi swap and the motor runs so strong i would hate to swap it just cuz the rings ya know but thanks for the help man

 

If you have done any motor work it isn't too hard. I did mine w/ the engine in the car and it ran solid for a while until I swapped the engine out for a B series.

You will likely have a ton of carbon build up on your head because of the burning oil, so the most expensive part would be having the head refreshed while it's out. You might be able to get by with cleaning the head surface yourself though. A ring expander tool, ring compressor, and cylinder hone would be required. NPR rings are the ones to go for, and you'd need items like VC gasket, oil pan gasket, and timing belt kit to get it all back together.

If it's something you want to pursue, I can provide more detail but the best start will be to study the factory service manual and be sure you understand what will be required.

 

i have done head work to timing belts and replaced my clutch before on my eg but never any motor work i need to find a factory service manual for sure whats a good one to get is it all online? i think i could take on the ring job just would def need to prepare my self before i did it and i guess like you said i should send my head out to get out cleaned and resurfaced but that should only cost me close to $200 and im cool with that ya man send me any info on how to do it and ill see if its something i can do
